If I configure SAI 2 in cubeMX I get a greyed out option that the synchronous slave is not available unless I have one SAI as master, but I have set SAI A as master (or master with master clock out). So what am I doing wrong?
It doesn't matter if I configure it for the A7NS or the cortex-m4, the option is greyed out.
The pins are available for both the SAI2 A/B
Is this a limitation of cubeMX? Or am I missing something?
Thanks, Robert

Hi @RZ ,
As the problem seems to come from STM32CubeMX, I suggest you to mux your pins manually in the Device Tree.

Thanks Armand, that was what I was looking for. RZ
